Abstract
A process for preparing a treated magnesium and/or magnesium alloy component comprising (A) treating the magnesium and/or magnesium alloy component with a surface treating agent containing a phosphate, (B) treating the component with a pre-treating agent used before a corrosion inhibition treatment, (C) treating the component, as required, with a cleaning agent containing surfactant and at least one compound selected from among aromatic carboxylic acids and salts thereof, and thereafter (D) treating the component further as required, with a corrosion inhibitor for magnesium.
